Fig. 3 — Model eye images obtained when the eye pupil was Φ5.68mm (SH 16 × 16) and the sampling aperture was set to (a) 20 × 20 SH sampling grid (Φ7.2mm) and (b) 14 × 14 SH sampling grid (Φ5.0mm). (c) is their wavefront rms comparison. The image resolution is improved by shrinking the pupil to avoid the slope errors at the wavefront boundary. Wavefront control accuracies with/without pupil adjustment differ by more than two log units.
